The following configuration generates a systemd unit that doesn't
start.
```nix
{
services.syncthing = {
enable = true;
user = "my-user";
};
}
```
It fails with
```
systemd[1]: Started Syncthing service.
systemd[6745]: syncthing.service: Failed to determine group credentials: No such process
systemd[6745]: syncthing.service: Failed at step GROUP spawning /nix/store/n1ydz3i08nqp1ajc50ycy1zribmphqc9-syncthing-1.1.4-bin/bin/syncthing: No such process
systemd[1]: syncthing.service: Main process exited, code=exited, status=216/GROUP
systemd[1]: syncthing.service: Failed with result 'exit-code'.
```
This is due to the fact that `syncthing` group (default) is not
created if the user is overridden.
Add a separate check for setting up the default group, so that
user/group are created independently.
This is a refactor of how resolvconf is managed on NixOS. We split it
into a separate service which is enabled internally depending on whether
we want /etc/resolv.conf to be managed by it. Various services now take
advantage of those configuration options.
We also now use systemd instead of activation scripts to update
resolv.conf.
NetworkManager now uses the right option for rc-manager DNS
automatically, so the configuration option shouldn't be exposed.
We were already creating a group for the user under which to run syncthing but
we were defaulting to running as `nogroup`.
Additionally, use `install` instead of multiple calls to mkdir/cp/chown.
Add an option to set the rc-manager parameter in NetworkManager.conf,
which controls how NetworkManager handles resolv.conf. This sets the
default rc-manager to "resolvconf", which solves #61490. It
additionally allows the user to change rc-manager without interference
from configuration activations.
Applies OpenWRT's noscan patch to hostapd and the relevant option to
the hostapd module.
This noscan patch adds a new `noscan` option allowing us to create
some overlapping BSSs in HT40+/- mode.
Note: this option is disabled by default, we leave this up to the end
user whether it should be enabled or not.
Not being able to create those overlapping BSSs is basically
preventing us to use 802.11n in any urban area where chances to
overlap with another SSID are extremely high.
The patch we are using is a courtesy of the openwrt team and is
applied to the defaul hostapd package in both OpenWRT and Archlinux.
The the extraConfig variable is added below the domain variable in the
ddclient config file. The domain variable should always be last.

Previously each oneshot peer service only ran once and was not
restarted together with the interface unit. Because of this,
defined peers were missing after restarting their corresponding
interface unit.

This can lead to unnecessary failures if the kernel module is already
loaded:
Jun 06 12:38:50 chef bglisn9bz0y5403vdw9hny0ij43r41jk-unit-script-wireguard-wg0-start[13261]: modprobe: FATAL: Module wireguard not found in directory /run/booted-system/kernel-modules/lib/modules/4.19.36
Types are now specified for all options.
The fixed uid and gid for the avahi user have been removed
and the user avahi is now in the group avahi.
The the generic opening of the firewall for UDP port 5353 is
now optional, but still defaults to true.
The option `extraServiceFiles` was added to specify avahi
service definitions, which are then placed in `/etc/avahi/services`.
Remove the btsync module. Bittorrent Sync was renamed to Resilio Sync in
2016, which is supported by the resilio module. Since Resilio Sync had
some security updates since 2016, it is not safe to run Bittorrent Sync
anymore.
Before, changing any peers caused the entire WireGuard interface to
be torn down and rebuilt. By configuring each peer in a separate
service we're able to only restart the affected peers.
Adding each peer individually also means individual peer
configurations can fail, but the overall interface and all other peers
will still be added.
A WireGuard peer's internal identifier is its public key. This means
it is the only reliable identifier to use for the systemd service.
When calling reload, bird attempts to reload the file that was given in
the command line. As the change of ${configFile} is never picked up,
bird will just reload the old file.
This way, the configuration is placed at a known location and updated.
As a oneshot service, if the startup failed it would never be attempted again.
This is problematic when peer's addresses require DNS. DNS may not be reliably available at
the time wireguard starts. Converting this to a simple service with Restart
and RestartAfter directives allows the service to be reattempted, but at
the cost of losing the oneshot semantics.

Passwords should not be stored in plain text by default. On existing
installations the next time a users user accounts will automatically
be upgraded from plain to hashed one-by-one as they log in.
With `sshd -t` config validation for SSH is possible. Until now, the
config generated by Nix was applied without any validation (which is
especially a problem for advanced config like `Match` blocks).
When deploying broken ssh config with nixops to a remote machine it gets
even harder to fix the problem due to the broken ssh that makes reverts
with nixops impossible.
This change performs the validation in a Nix build environment by
creating a store path with the config and generating a mocked host key
which seems to be needed for the validation. With a broken config, the
deployment already fails during the build of the derivation.
The original attempt was done in #56345 by adding a submodule for Match
groups to make it harder screwing that up, however that made the module
far more complex and config should be described in an easier way as
described in NixOS/rfcs#42.
I noticed xinetd process doesn't get exec'd on launch, exec here so the bash
process doesn't stick around.

The type of ZNC's config option specifies that a configuration like
config.User.paul = null;
should be valid, which is useful for clearing/disabling property sets
like Users and Networks. However until now the config generator
implementation didn't actually cover null values, meaning you'd get an
error like
error: value is null while a set was expected, at /foo.nix:29:10
This fixes the implementation to correcly allow clearing of property
sets.
This allows configuring IP addresses on a tinc interface using
networking.interfaces."tinc.${n}".ipv[46].addresses.
Previously, this would fail with timeouts, because of the dependency
chain
tinc.${netname}.service
--after--> network.target
--after--> network-addresses-tinc.${n}.service (and network-link-…)
--after--> sys-subsystem-net-devices-tinc.${n}.device
But the network interface doesn't exist until tinc creates it! So
systemd waits in vain for the interface to appear, and by then the
network-addresses-* and network-link-* units have failed. This leads
to the network link not being brought up and the network addresses not
being assigned, which in turn stops tinc from actually working.
Ideally, private keys never leave the host they're generated on - like
SSH. Setting generatePrivateKeyFile to true causes the PK to be
generate automatically.
This is an implementation of wireguard support using wg-quick config
generation.
This seems preferrable to the existing wireguard support because
it handles many more routing and resolvconf edge cases than the
current wireguard support.
It also includes work-arounds to make key files work.
This has one quirk:
We need to set reverse path checking in the firewall to false because
it interferes with the way wg-quick sets up its routing.
